Solid advice, but I would say a trillionaire could spend less in most of these categories. If I'm a trillionaire, my healthcare, housing and transportation needs are not all that different from thousandaires :) the biggest difference would be my savings rate and discretionary income. Hedonic adaptation tells us to continue to spend at the same rate as our income increases, but is that necessary?
Overall I think this is fantastic advice for someone new to controlling their expenses. Thanks for sharing!
